the average temperature of the first three days of a week is 26.5 degree and that next three days is 29 degree celsius.i f the weekly average is 27.4 degree celsius then what's the temperature of the last days

Answer»

Let last temperature is X

Total average = (1ST avg + 2nd avg + x) / 3

27.4 = (26.5 + 29 + x)/ 3

82.2 = 55.5 + x

x = 26.7 degree

7th DAY TEMPERATUR is 26.7 degree
